不同变形温度下7050铝合金的动态析出行为分析
Dynamic Precipitation Behavior of Aluminum Alloy7050 Under Different Deformation Temperature
摘要
Abstract
The dynamic precipitation behavior of the nano particles MgZn2 in aluminum alloy 7050 under different deformation temperatures was investigated.The results show that the fluctuation of hot deformation curve of aluminum alloy 7050 is irrelevant to dynamic strain aging,while the fluctuation is caused by dynamic recrystallization of the alloy.The hot deformation prompts the precipitation of MgZn2,and the precipitation amount decreases with the increase of the temperature.The grain size of the precipitation at grain boundary is lager than that of intracrystalline.There are two kinds of formations for the phase MgZn2 during the high-speed deformation of the aluminum alloy7050,and the integration between the two formations and matrix improves the crack problems during the deformation of the alloy.关键词
